Answer 2

1. 8x < 722:

To solve this inequality, divide both sides by 8: x < 722/8 x < 90.25

So the solution to the inequality is x < 90.25.

2. -15x ≤ 25:

To solve this inequality, divide both sides by -15. When dividing by a negative number, remember to flip the inequality sign: x ≥ 25/(-15) x ≥ -5/3

So the solution to the inequality is x ≥ -5/3.

3. x/3 > 44:

To solve this inequality, multiply both sides by 3. Since we are multiplying by a positive number, the inequality sign remains the same: x > 44 * 3 x > 132

So the solution to the inequality is x > 132.

4. 3(2 + x) > 4 - x:

First, simplify both sides of the inequality: 6 + 3x > 4 - x

Combine like terms: 3x + x > 4 - 6 4x > -2

Divide both sides by 4 (a positive number): x > -2/4 x > -0.5

So the solution to the inequality is x > -0.5.

5. -(2 - 3x) + 4(6 + x) ≥ 1:

First, simplify both sides of the inequality: -2 + 3x + 24 + 4x ≥ 1

Combine like terms: 7x + 22 ≥ 1

Subtract 22 from both sides: 7x ≥ 1 - 22 7x ≥ -21

Divide both sides by 7 (a positive number): x ≥ -21/7 x ≥ -3

So the solution to the inequality is x ≥ -3.
